When using the Virtual Tone Wheel Organ (VTW) on the FANTOM 6, FANTOM 7, or FANTOM 8, the Register 1’ harmonic bar does not produce sound when the Percussion parameter is enabled.
This occurs because the instrument follows the design of traditional tone wheel organs. In those models, the 1’ harmonic bar is internally assigned to control the percussion function, and as a result, it becomes muted when Percussion is active.
